Helenium plant named ‘Ranchera’

ABSTRACT

A new and distinct cultivar of  Helenium  plant named ‘Ranchera’ characterized by its compact, broadly upright and uniformly mounding plant habit; moderately vigorous growth habit; freely flowering habit; inflorescences with dark orange-colored ray florets; and strong peduncles that hold the inflorescences above the foliar plane.

Botanical designation: Helenium autumnale.

Cultivar denomination: ‘RANCHERA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Helenium plant, botanically known as Helenium autumnale and hereinafter referred to by the name ‘Ranchera’.

The new Helenium plant is a product of a planned breeding program conducted by the Inventor in Zuidwolde, The Netherlands. The objective of the program is to create and develop new compact and freely-flowering Helenium plants with attractive ray and disc colors.

The new Helenium plant originated from an open-pollination in 2010 of an unidentified selection of Helenium autumnale, not patented, as the female, or seed, parent with an unknown selection of Helenium autumnale as the male, or pollen, parent. The new Helenium plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Zuidwolde, The Netherlands in 2012.

Asexual reproduction of the new Helenium plant by terminal cuttings in a controlled greenhouse environment in Zuidwolde, The Netherlands since June, 2014 has shown that the unique features of this new Helenium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Helenium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ranchera’. These characteristics in combination distinguish ‘Ranchera’ as a new and distinct Helenium plant:

-   -   1. Compact, broadly upright and uniformly mounding plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely flowering habit.     -   4. Inflorescences with dark orange-colored ray florets.     -   5. Strong peduncles that hold the inflorescences above the         foliar plane.

In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Helenium differ from plants of the female parent selection primarily in plant habit as plants of the new Helenium are more uniformly mounding than plants of the female parent selection.

Plants of the new Helenium can be compared to plants of Helenium hybrida ‘Salsa’, disclosed in U.S. Plant Pat. No. 25,978. In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Helenium differed from plants of ‘Salsa’ in the following characteristics:

-   -   1. Plants of the new Helenium were more compact than plants of         ‘Salsa’.     -   2. Plants of the new Helenium and ‘Salsa’ differed slightly in         ray floret color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn in containers and ground beds in an outdoor nursery in Zuidwolde, The Netherlands and under cultural practices typical of commercial Helenium production. During the production of the plants, day temperatures ranged from 15° C. to 25° C. and night temperatures ranged from 3° C. to 15° C. Plants were two years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
